Abstract: A data center interconnection (DCI) network may comprise a data center controller (DCC) managing a plurality of data centers (DCs) interconnected by a provider network managed by a network provider controller (NPC). The provider network may be an OpenFlow based software defined networking (SDN) transport network. The DCC may initiate a virtual network service (VNS) negotiation with the NPC to connect the DCs and may specify a network abstraction granularity level. The NPC may respond by computing paths through the provider network accordingly and providing the DCC with one or more virtual networks (VNs). The DCC may compute virtual paths through the VNs and send virtual network element (VNE) connection setup commands to the DCC. The DCC may convert the VNE connection setup commands into network element (NE) commands to setup connections in NEs of the provider network. The DCC and the NPC may perform fault monitoring, detection, and recovery.

Abstract translation: 数据中心互连（DCI）网络可以包括管理由网络提供者控制器（NPC）管理的提供商网络互连的多个数据中心（DC）的数据中心控制器（DCC）。 提供商网络可以是基于OpenFlow的软件定义网络（SDN）传输网络。 DCC可以发起与NPC的虚拟网络服务（VNS）协商以连接DC，并且可以指定网络抽象粒度级别。 NPC可以相应地通过提供商网络的计算路径进行响应，并向DCC提供一个或多个虚拟网络（VN）。 DCC可以通过VN计算虚拟路径，并向DCC发送虚拟网元（VNE）连接建立命令。 DCC可以将VNE连接设置命令转换为网元（NE）命令，以在提供商网络的网元中设置连接。 DCC和NPC可以执行故障监控，检测和恢复。
